GATP’s business tax preparation services include deadline tracking so you never miss a due date.

For small business tax preparation, you’ll typically need: profit & loss statements, balance sheet, bank and credit card statements, payroll records and W-2s/1099s, receipts for deductible expenses, prior year’s business tax returns, and EIN documentation. GATP provides a personalized document checklist when you onboard.
What are common tax deductions for small businesses?
Common deductions include home office expenses, business vehicle use, employee salaries and benefits, software and equipment (Section 179), marketing and advertising costs, professional services (legal, accounting), health insurance premiums, and retirement plan contributions.
What do I need to give my tax preparer for my business?
Provide complete and accurate financial data, including income records, expenses, prior returns, and any relevant tax documents to ensure smooth business tax preparation services.
